Hi Slyhee! Itch.io only supports Paypal or Stripe and sadly the credit card option from Stripe doesn't allow my country to register. :(
The price on Patreon is basically the same but on Itch.io there is a sale and I don't know how to setup sale on Patreon yet. Please message me via my Discord Sang Hendrix#3505 so I can support you more easily.
